Milan,
why do not you use non-solder mask and double-sided PCBs? |

Hi Pavel!
If you take a closer look at my website, you'll see that I usually do use silk screen double-sided PCBs. However, my Academia is still a prototype and I prefer to design, draw and etch all my prototype boards myself. One of the reasons is that I actually enjoy designing, drawing and etching my own boards, winding my own transformers, building my own cases, tweaking capacitors and pulling all sorts of crazy stunts like that in the line of DIY duty. ![]() Of course, it is a whole other story when it comes to my professional audio designs. ![]() Regards, Milan |

![]() ![]() Lineup most Advanced HiFi Headphone Amplifier This headphone amplifier was built like 10 years ago. Circuit, layout and everything is my very own idea & design. As you can see, ![]() ![]() This is the theoretically superior method. Not always easy and practical. But good! As well known: There is no better quality electrical insulator, than AIR. Not even some fancy plastic or epoxi variants Dupont or PFTEX Extra AudioPhile PCB boards! Audio people may not know this, as often as Radio Amateurs do. What is best quality Variable capacitors? The Radio Amateur will tell you: AIR Insulated variable capacitor. This is The only option for a high performance. He will not tell you using some plastic insulation cap. Like PTFE or Polyproylene No! ------------------------------- ![]() Nice, isn't it? These are BD139 / BD140 push-pull TRUE CLASS A followers. ![]() ![]() /lineup - chief director of production line
